802.11b Standards-based Wireless Networking
The DG824M gateway includes an 802.11b-compliant wireless access point, providing
continuous, high-speed 11 Mbps access between your wireless and Ethernet devices. The access
point provides:
• 802.11b Standards-based wireless networking at up to 11 Mbps
• 64-bit and 128-bit WEP encryption security
• WEP keys can be generated manually or by passphrase
• Wireless access can be restricted by MAC address.
A Powerful, True Firewall
Unlike simple Internet sharing NAT routers, the DG824M is a true firewall, using stateful packet
inspection to defend against hacker attacks. Its firewall features include:
• Denial of Service (DoS) protection
Automatically detects and thwarts Denial of Service (DoS) attacks such as Ping of Death,
SYN Flood, LAND Attack and IP Spoofing.
• Blocks unwanted traffic from the Internet to your LAN.
• Blocks access from your LAN to Internet locations or services that you specify as off-limits.
• Logs security incidents
The DG824M will log security events such as blocked incoming traffic, port scans, attacks,
and administrator logins. You can configure the gateway to email the log to you at specified
intervals. You can also configure the gateway to send immediate alert messages to your email
address or email pager whenever a significant event occurs.
